No. 853,109.k

Specification of Letters Patent.

Patented' May 7, 1907.

Application filed April 27.1906. Serial No. 313.996.

.To all whom, it may concern:

Be it known that I, ,ELMER NrcHosoN, a

citizen of the United States, and a resident of Lansing, in the county lof Ingham and State of Michigan, have invented a new and Improved Vibrating Roller for Printing- Presses, of lwhich the following isa full,

clear, and exact description.

The purpose of the invention is to provide a color vibrator for printing presses adapted for use in connection with dlstributing rollers Where different colors are to be printed at one impression, and to provide a sim le and effective device capable of being quic ly and conveniently set up for adaptation to any desired number of colors,and to act in conjunction with distributing rollers of the ordinary t e. o

ypAnother purpose of the invention is to render it possible to so adjust thev color vi-` brating sections of the vibrating roller that adjacent colors will not' be run 'one into the other, and so that the belts of colors may be of the saine or of'varying Widths.

, The invention consists in the novel construction and combination of the several parts, as will be hereinafter fully set forth 4an'd pointed out in the claims.

Reference is to be `had to the vaccompanying drawings forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the iigures.v

Figure .1 is a plan view of a portion of a pony cylinder color press and the improved vibrator applied thereto; Fig. 2 is a longitudinal section through the improved vibrating roller; F ig. 3a is a longitudinal sectionv through a portion of the vibrating roller and a portion of the distributing roller, illustrating the initial or intermediate position of a` distributing section of the vibrating roller relative to .the form roller; Fig. 3b is a view ing roller is at the end of its stroke in one direct-ion; and Fig. 30 is a View similar to those shown in Figs. 3a and 3b, but illustrating 'the extent of the distributed surface when the distributing section of the vibrating roller,

23 in the has reached the limit of its stroke in the opposite direction; and Fig. 4 1s an enlarged'l transverse section through the vibrating roller.

The vibrating roller A consists of a shaft 1'0 of suitable length, having a collar 1-1 near one end, and a fixed grooved wheel 12 or its equivalent at the adjacent extremity; and neargfthe opposite end of the shaft 10 two closelyT related threaded surfaces 13 and 14 are produced, the inner one being of greater diameter than the outer one; and one of said surfaces has a "left and the other one has a right-hand thread thereon, to receive lock and jam nuts 15 and 16; and in the further construction of the shaft 10 a key 17 is formedthereon, extending from the collar 11 to the outer threaded surface 13, as is illustrated in Fig. 2. Y

The shaft 10 carries series of cylindrical sections, said cylindrical sections 18'of one series being of a desired diameter, but the they operate, as is shown in Figs. 3a, 3l and 3.

The distributing rollers A may be of any desired type, and are provided with the customary shafts a. y

The cylindrical sections 18 and 19 of the vibrating roller A are made in different lengths, so that any desired number of spaced color-distributing surfaces may be obtained, each of any desired length and' spaced any desired or necessary distance apart, as may be called for in settinr up the vibrting roller A for the different inds of wor Each cylindrical section-18 and 19 is provided With a bore 20, extending throu h from end to end, and a groove 21 in the Wa l of the bore, as shown in Fig. 4, so that While the cylindrical sections 1S and 19 ma be readily slipped upon or removed from tlie they are prevented from turning on the shaft, and when the cylindrical sections are in position on the shaft they are locked end to end by the collar 11 and the nuts 15 and 16.

In Fig. 1 I have .shown the adaptation of the improved vibrating roller to a pony press B toprintfour circular letters at one time in va multiple of colors, and four full page forms 22 are shownon the press locked in avchase customary manner. The ink fountain 24 is of the ordinary type, each color 25 being laid for proper distribution to the appropriate type, and each color is backed or shaft 19, v

- l impression cylinder 28jand its fly 29.

.held in place or separated in the usual Lmanner by 'Waddedtissue paper, or rags, for example. The vibrating roller A is set up so that the distributing sections 18 cover the i.

vtypefto which ink ofthe chosen color is to be applied, lso as to'insure the covering Vof said typeaisthe' sections pass back andk forth, the

j. spaces 4between the distributing Vsections 18 o the y*vibrating rollerv A being filled in by spacing. sections 1'9of proper length. The spacingofA the' distributingfs'ecti'ons' 18 is so calculated that l.in the operationof the vibrating roller A one color will not b rubbed into another,v v'and such calculation will defpend upon the extent of the throw of the said lvibrating roller, it being the aim to so set'the distributing sections 18- that they Will disJ tribute thcolors on the form rollers .ft/With i' in about an. eighth of an)1 inchjof each other.

The operation o fthefcolor distributing secl tions 18 relative to the form roller A is -clearlyt'shown in Figs'.' 8.a, 3b and 3c, wherein in Fig. 3 the color 25 is just deposited upon the form roller, While in Fig. 3l the color 25`is shown spread in one direction, and in Fig. 3c as spread in an opposite direction, complet- -ing the Width of the color belt. Further `parts ofthe presssliowngin Fig. 1 consist of the ink roller 26 and its doctor 27 Which-de'- as for example by a fork given a vibrat'ory 3S -livers the ink to the vibrating roller. A, the

The grooved wheel `12 of thev vibrating roller A ls agitated in any approvedmanner,

-movement -through a suitable connection with the driving.mechanism of the ress.

The improved vibrating roller is a aptable to any form of press, .and may be used in running any desired number of colors. It saves time of the feeder, Wear'upon the machine, powerl and time to Inakeready, and

number of cells for different colors of ink, and a forni roller Aoperating in conjunction With the said fountain, of a vibrating inking roller adapted to take ink from said fountain, and consisting of a shaft, a series of removable shaft, the spacing sections being of lesser diameter than the diameter of the distributing sponding in length, in number and arrange-` ment 'to the length, number and arrangement of the cells in theink fountainfthe vibratirm of said inking roller and the relationof the distributing section-k thereof being` such that the ink of one color received by the roller Will be sharply defined from an adjoining color also received by the roller, one color being 4end of the shaft, and locking nuts for the sections at the opposite ends of the shaft, the sections being held by the locking devices named, in close end engagement fle With the othen 4 In testimony Whereof I have signed my name' to this speciiication in the presence of two subscribing Witnesses.` 4
